Product Overview
The AO3400A is an N-channel enhancement-mode MOSFET designed for low-voltage power switching, load control, and PWM applications. It features a 30V drain-source voltage rating, 5.7A continuous drain current at 25°C, and very low drain-source on-resistance down to 26.5mΩ at a 10V gate drive. Its low gate charge and low RDS(on) at 2.5V, 4.5V, and 10V gate drive levels make it suitable for efficient logic-controlled switching.
Packaged in a compact SOT-23 surface-mount package, the AO3400A is well suited to battery-powered electronics, DC power distribution, load switching, and compact power-management circuits where low conduction loss and small PCB size are important.
